But a very small portion of human activity is developing chips or launching rockets. Most of it is manufacturing disposable junk or building roads/buildings.

Good vid from real engineering on the subject

SpaceX launches in 2023 were about 0.02 megatons of CO2 directly. I don’t know how fugitive emissions from fueling and defueling, especially on starship with methane.

200,000kg/launch, 100 launches.

I don’t have access to dig though it right now, but I thought the NASA paper showed couple percent increase in ozone deterioration.

Plastic takes thousands of years to decompose, so wouldn’t it act as a carbon sink until then?

96 as of September 29 https://spaceexplored.com/spacex-launches-2024/

And they’re on track for ~130 this year.

Hmm, if we’re saying everything is done with green energy, could plastic bottles be carbon negative? Make the plastic from algie or bean feed stock so that it acts as a form of carbon capture.

At least that means they don’t plan to use them for an invasion soon?

How many percent is it?

I think that’s a whole lot less plastic than if it was the whole thing.

One way is to put the link into something like this. https://twittervideodownloader.com/download

I don’t think Twitter mirrors work any more unfortunately.

If you have single use bottles, aluminum like soda cans is lowest impact. But any reusable solution (meal, plastic, or glass) is much much better.

Reusable plastic bottles or metal are great, it’s the single use plastics that are really terrible.

Because we have reason to believe those things might be harmful. We do need much more research to see how harmful they are to ozone, since the one paper’s conclusion was that tens of thousands of satellites re-entering each year may have a percent or two effect on ozone. But I don’t see why we would ban rockets that we have no reason to believe hurt ozone.

How does that relate to what I said? Starship has not launched any payloads yet. Your original comment said this rocket should be banned because it depletes ozone. It doesn’t. You should say we should outlaw SRBs, soot trails, and aluminum satellite reentry, not ban starship or rockets in general.

Nope, this was a test launch.

That is satellite reentry, nothing to do with rocket launches. Building satellites out of something other than aluminum solves the issue, but even with mega consolations the effect is not super significant.

Like charges repel. Putting raw electrons in a container would make a really good bomb.

Plus, the electrons would make new elements as they run into other atoms. You’d need electromagnetic containment to keep it from coming into contact with anything. Come to think about it, that’s pretty much what a particle accelerator is.
